This volume presents a collection of essays devoted to the analysis of scientific change and stability. It explores the balance and tension that exist between commensurability and continuity on the one hand and incommensurability and discontinuity on the other. The book constitutes fully revised versions of papers that were originally presented at an international colloquium held at the University of Nancy, France, in June 2004.

The present volume aims at giving a discussion ot the problems ot reductionism in contemporary life sciences. It contains six papers which deals with reduction/reductionism in different fields ot biological research. Also, the holistic perspective, 1. e. the systems view, is discussed in some ot the papers. The message ot this discussion Is that - whereas reductionism is indeed an important strategy - the systems approach is needed. It is argued by some ot the authors that organisms are complex systems and not just heaps of molecules, 50 that the analytical method does not suffice. Recent developments in systems theory offer the possibility to install a more comprehensive view ot living systems what can be seen particularly in the field ot evolutionary biology. It is true that any organismic activity is molecular, this is to say that it is based on molecular mechanisms. But it is also true that the whole organism displays certain patterns ot behavior which are not just molecular. Any organism can be described as a system ot different levels ot organization different levels ot order and complexity - and it is important, theretore, to study all ot the organizational levels and to see their peculiarities. It should be obvious, however, that there is not one problem ot reduction/reductionism, but that there are many problems linked together and that these problems appear at different levels ot biological research and bio philosophical reflections."

Incommensurability and Related Matters draws together some of the most distinguished contributors to the critical literature on the problem of the incommensurability of scientific theories. It addresses all the various problems raised by the problem of incommensurability, such as meaning change, reference of theoretical terms, scientific realism and anti-realism, rationality of theory choice, cognitive aspects of conceptual change, as well as exploring the broader implications of incommensurability for cultural difference. While it offers new work, and new directions of discussion, on the topic of incommensurability, the book also recapitulates the history of the discussion of the topic that has taken place within the literature on incommensurability.

The volume is a collection of essays devoted to the analysis of scientific change and stability. It explores the balance and tension that exists between commensurability and continuity on the one hand, and incommensurability and discontinuity on the other. And it discusses some central epistemological consequences regarding the nature of scientific progress, rationality and realism. In relation to these topics, it investigates a number of new avenues and revisits some familiar issues, with a focus on the history and philosophy of physics, and an emphasis on developments in cognitive sciences as well as on the claims of new experimentalists.The book is constituted of fully revised versions of papers which were originally presented at the international colloquium held at the University of Nancy, France, in June 2004. Each paper is followed by a critical commentary.

Ich traf Paul Hoyningen das erste Mal Mitte August 1984, als er in Boston an- kam, um einJahr am Massachusetts Institute of Technology zu verbringen. Wir wa- ren beide etwas besorgt: Der Besuch war ein Experiment, und keiner van uns konnte sicher sein, dass er erfolgreich sein wtirde. Sein projekt war ein Buch liber meine philosophische Arbeit, ganz besonders liber, Die Struktur wissenschaflli- cher Revolutionen'. Nachdem er meine Schriften mehrere Jahre lang studiert hatte, wollte er nun seine Resultate durch ausfUhrliche Diskussionen mit mir erg?nzen. Seine Initiative war van liberzeugenden Empfehlungsschreiben begleitetj ich be- griisste sie und hatte Hilfe versprochen. Aber ich war als jemand bekannt, der vieI Arbeit hatte und der reizbar war, speziell Leuten gegenliber - mir schienen sie-sehr zahlreich -, die darauf bestanden, dass sie in meinen Arbeiten Ideen f?nden, die dort liberhaupt keinen Platz hatten, und van denen ich einige abgelehnt hatte. Wenn ich auf seine Ansichten auf die gleiche Weise reagieren wtirde, dann wtir- den wir beide Schwierigkeiten bekommen. Unser Engagement fUr das kommcnde J ahr war unwiderruflich gegeben.

Few philosophers of science have influenced as many readers as Thomas S. Kuhn. Yet no comprehensive study of his ideas has existed--until now. In this volume, Paul Hoyningen-Huene examines Kuhn's work over four decades, from the days before "The Structure of Scientific Revolutions" to the present, and puts Kuhn's philosophical development in a historical framework.
Scholars from disciplines as diverse as political science and art history have offered widely differing interpretations of Kuhn's ideas, appropriating his notions of paradigm shifts and revolutions to fit their own theories, however imperfectly. Hoyningen-Huene does not merely offer another interpretation--he brings Kuhn's work into focus with rigorous philosophical analysis. Through extended discussions with Kuhn and an encyclopedic reading of his work, Hoyningen-Huene looks at the problems and justifications of his claims and determines how his theories might be expanded. Most significantly, he discovers that "The Structure of Scientific Revolutions" can be understood only with reference to the historiographic foundation of Kuhn's philosophy.
Discussing the concepts of paradigms, paradigm shifts, normal science, and scientific revolutions, Hoyningen-Huene traces their evolution to Kuhn's experience as a historian of contemporary science. From here, Hoyningen-Huene examines Kuhn's well-known thesis that scientists on opposite sides of a revolutionary divide "work in different worlds," explaining Kuhn's notion of a world-change during a scientific revolution. He even considers Kuhn's most controversial claims--his attack on the distinction between the contexts of discovery and justification and his notion of incommensurability--addressing both criticisms and defenses of these ideas.
Destined to become the authoritative philosophical study of Kuhn's work, "Reconstructing Scientific Revolutions" both enriches our understanding of Kuhn and provides powerful interpretive tools for bridging Continental and Anglo-American philosophical traditions.

In Systematicity, Paul Hoyningen-Huene answers the question "What is science?" by proposing that scientific knowledge is primarily distinguished from other forms of knowledge, especially everyday knowledge, by being more systematic. "Science" is here understood in the broadest possible sense, encompassing not only the natural sciences but also mathematics, the social sciences, and the humanities. The author develops his thesis in nine dimensions in which it is claimed that science is more systematic than other forms of knowledge: regarding descriptions, explanations, predictions, the defense of knowledge claims, critical discourse, epistemic connectedness, an ideal of completeness, knowledge generation, and the representation of knowledge. He compares his view with positions on the question held by philosophers from Aristotle to Nicholas Rescher. The book concludes with an exploration of some consequences of Hoyningen-Huene's view concerning the genesis and dynamics of science, the relationship of science and common sense, normative implications of the thesis, and the demarcation criterion between science and pseudo-science.

Many texts on logic are written with a mathematical emphasis, and focus primarily on the development of a formal apparatus and associated techniques. In other, more philosophical texts, the topic is often presented as an indulgent collection of musings on issues for which technical solutions have long since been devised.

What has been missing until now is an attempt to unite the motives underlying both approaches. Paul Hoyningen-Huene's "Formal Logic" seeks to find a balance between the necessity of formal considerations and the importance of full reflection and explanation about the seemingly arbitrary steps that occasionally confound even the most serious student of logic. Alex Levine's artful translation conveys both the content and style of the German edition. Filled with examples, exercises, and a straightforward look at some of the most common problems in teaching the subject, this work is eminently suitable for the classroom.
